During the show, she asked concertgoers: "Who''s registered to vote?" She then added that she didn't care who they voted for, "as long as you vote for Obama."

The 54-year-old, however, quickly changed her tune when she heard the crowd''s reaction, the New York Daily News reported. u00a0"Seriously, I don''t care who you vote for ... Do not take this privilege for granted. Go vote," she continued.

This is not the first time Madonna has drawn criticism for making a political statement on her MDNA tour.u00a0
The pop star confused fans in September when she told them to support the "black Muslim in the White House" at a Washington, D.C. concert.
